Well, you shouldn't use it as a permanent green screen, but I think it's great for on the go. First, it's not a typical light green shade key, it's darker (but I think it will work quite well). Second, as it is polyester, it is very wrinkled and needs to be ironed carefully to get a smooth finish. Third, it is very transparent and see-through, so you need to make sure there is no window or light source behind the green screen. Finally, it's really hard to figure out how to fold it, but that's the least of my worries. I'll probably have to relearn and figure it out every time when I put it back in the suitcase! AND THE GOOD THING IS THAT IT COMES WITH A CASE because it wasn't mentioned in the description. I haven't tried it to see how it sits on the back of my chair, but I can tweak the feedback if that's acceptable for some reason.
